Within the Lobes
The largest lobe in the human brain; the most common region of brain trauma/injury
What is the frontal lobe?
An extension of the central nervous system that carries nerve signals between the brain and the body
What is the spinal cord?
This largest part of the brain handles conscious thoughts and actions and contains two hemispheres
What is the Cerebrum?
Abbreviated RAS, this network of NERVE pathways in the brainstem connects the Spinal Cord, Cerebrum, and Cerebellums
What is the Reticular Activating System?
The part of the brain lying beneath the temples that processes auditory information and encodes memory
What is the temporal lobe?
The topmost part of the brainstem; this connects the brain and the spinal cord with its three main parts being the colliculi, tegmentum, and the cerebral peduncles
What is the Midbrain?
This region of the brain contains motor neurons involved in the comprehension of speech and is located in the left posterior superior temporal gyrus
What is Wernicke’s Aea?
When this part of the brain is damaged, it may lead to dysfunction in the senses
What is the Parietal Lobe?
A complex brain structure that lies deep in the temporal lobe and plays a major role in learning and memory
What is the hippocampus?
Linking the Medulla Oblongata and the Thalamus, these parts of the brainstem is a vital section of the nervous system
What are pons?
A part of the brain located at the back of the head that coordinates movement and times muscle actions for smooth bodily movement
What is the Cerebellum?
A part of the brain lying above the brainstem with nerve fibers connecting the cerebral cortex in all directions; all information from your body’s senses (except smell) must be processed here
What is the thalamus?
This area of the brain is the rearmost in each cerebral hemisphere, and its main function is visual perception, including color, form, and motion
What is the occipital lobe?
This is the bottom most-part of the brain that sends signals for involuntary processes such as breathing and heart rate
What is the Medulla Oblongata?
Lying below the thalamus and above the pituitary gland, this region of the forebrain keeps the body in a stable state called homeostasis
What is the hypothalamus?
A large bundle of more than 200 million nerve fibers that connect the two brain hemispheres; this permits communication between the right and left sides of the brain
What is the Corpus Callosum?
This cortical area specializes in speech production and is found in the left inferior frontal gyrus
What is Broca’s Area?
What was the major discovery following the accident of Phineas Gage, whose frontal lobe was damaged with a metal rod?
The discovery that different parts of the brain affect different aspects of the human body
